The products of cracking are a mixture of hydrocarbons, ranging in carbon number from C1 to C10. These include:
- Methane (CH4) and Ethane (C2H6): These are the lightest products and are important for fuel production.
- Alkenes (e.g., Ethene, Propene): These are unsaturated hydrocarbons and are valuable as chemical feedstocks for the production of plastics and other chemicals.
- Alkanes (e.g., Pentane, Hexane): These are saturated hydrocarbons and are used as fuels.
Adjusting Conditions for Specific Products:
- Temperature: Higher temperatures favour the formation of smaller molecules (more methane and ethane). Lower temperatures favour the formation of larger molecules (more alkanes).
- Pressure: Higher pressures can shift the equilibrium towards the formation of smaller molecules.
- Catalyst: The type of catalyst used can influence the product distribution. For example, zeolite catalysts can be designed to favour the formation of specific alkene products.
